SEZEIGIFICATION forming part of Letters Patent No. 677,591, dated July2, 1901.

Application filed July 9, 1398- Serial No. 685,545. (No model.)

To @ZZ whom, t may cm2/cern:

Beit known that I, HARVEY S. PAGE, a citizen of the United States,residing at the cityof St. Louis, in the State of Missouri, haveinvented certain new and useful Improvements in Broom-Sewing Machines,of which the following is a full, clear, and' exact description,reference being had to the accompanying drawings, forming a part of thisspecilication. It is the object of my invention to provide a devicecapable of being easily operated by hand for sewing a plurality ofthreads through Abroom-holding jaws.

a broom. My device sews the required number of threads at one operationand is manipulated by hand. It possesses features of noveltyhereinafterfullypointed outand claimed. I accomplish this object bymeans of the machine illustrated in the accompanying drawings, in which-Figure 1 shows atop View of the device. Fig. 2 shows a front elevationof the jaws for clamping the broom and the needles and their carriages.Fig. 3 is a side elevation looking from the right of Fig. 1. Fig. 4 is adetail side view ot' one of the cam devices which guide the threader.Fig. 5 is a detail side View of the threader-retaining mechanism. Fig. Gis a vertical section taken through the Fig. 7 is a detail View of theelastic grip which holds the threadsin place.

I have distinguished the parts on the left side of the device from thoseon the right by numerals bearing prime-marks.

1 and 1' are standards on which the entire machine is supported. Thestandard 1 is fixed and the other, 1', is mounted on a pivot at thebottom, so as to be capable of being swung to and from the standard 1 bymeans of links 3, operated by toggle-links 4 and 5, the link 4constituting a hand-lever. The eX- tent of the movement is limited by asetscrew 6. Securely bolted or otherwise secured to the standards 1 andl' are jaws 7 and 7', between which the broom-straw, tied into a bundleand to be sewed, is securely clamped, the jaws being held by thetogglelinks and 5. These jaws are furnished with slots through which theneedles of the machine may pass, said slots being of greater length thanthe width of the broom to be sewed. Secured to the jaws and occupyingthe slots therein are prongs S and 8', that serve to support the twinewith which the broom is sewed.

On the standards 1 and 1' are lixed guides 9 and 9', that extend fromfront to rear 0f the machine and are dovetailed to receive slides 10 and10', that operate thereon. At

the outer edge of the guides 9 and 9' are racksv ll and 11', the teethof which are of approximately the same length as the length of thestitches to be made in sewing the broom, as will be hereinafterexplained. Fixed to the slides 10 and 10' are channeled bars 12 and 12'.These channeled bars are set at slight inclines to the slides, as seenin Fig. l, so that the needle-carriers which operate therein may becarried inwardly at an incline with relation to the broom in order thatthe needles may be forced through the broom at angles to the sidesthereof, thereby providing for the production of stitches running atangles across the broom instead of transversely.

13 and 13' are slides loosely seated in the channels of the bars 12 and12', adapted to be moved inwardly and outwardly in said channel-bars toand from the broom-holding jaws. These slides carry needles 14 and 14',the

needles being of the kind usually used in broom -sewing machines. Thenumber of needles corresponds to the number of rows of stitches to bemade in the broom, and the needles are arranged one above the other,occupying positions that enable their passage through the slots in thejaws 7 and 7'. By referring to Fig. 2 it will be observed that the eyesof the needles ou the slide 13 open downwardly, while those carried bythe slide 13' open upwardly.

15 and l5' are hand-levers pivoted at 16 and 16' to the slides 10 and10. These levers pass loosely through openings in the needlecarryingslides 13 and 13', and when the levers are moved they serve to move theslides 13 and 13 inwardly and outwardly in the channels of the bars 12and 12'. The outer ends of the channeled bars 12 and 12' are connectedto the rear ends of the slides 10 and 10 by braces 17 and 17'.

18 and 1S' designate slide-bars, which I will hereinafter call threadersThese thread- IOG ers are movably mounted above the slides 10 and 10',their length extending parallel of the length of the said slides andthey being adapted to operate backward and forwardly to and from thepath of the needles in the passage of said needles to the broom-holdingjaws.

19 and 19 are strips of rubber secured to the'forward ends of thethreaders, the said strips being provided with a series of slitscorresponding to the number of needles and likewise to the number ofrows ot' stitches to be produced in sewing the broom. These strips 19and 19' serve as a tension device for the sewingftwine, the twinepassing through the slits therein, where it is held in position to becaught by the needles.

The threaders 18 and 18' are arranged to be projected forwardly bysprings 2O and 20 in the manner to be hereinafter particularly pointedout. l

2l and 21 are dogs pivoted at 22 and 22' to brackets carried by theslides 10 and 10'.

23 and 23' are cani members pivoted to the slides at 34 and 34.

2e and 24e' are upright flat -spring posts fixed to the slides 10 andl0' near the rear ends thereof.

26 and 26 designate what I term drivers,7 provided with studs 25 and 25at their sides, adapted to engage the rear edges of the flat springs 24and 24. These drivers are pivoted to hangers 30 30 (see Figs. 3 and 5)and are capable of rocking on said pivot. The drivers are pivoted to thethreaders 18 and 18', and their upper ends extend rearwardly in a curveupon which the lugs 25 and 25l are carried. The pivots connecting thethreaders and drivers join them, so that they are required to move inunison.

-28 and 28' designate links one end of each of which is connected to thepivot that joins the threaders and drivers. The opposite end of eachlink carries a pin 28, engaged in the threaders 18 and 18.

29 and 29 are cam-grooves in standards and 33', mounted on the slides 10and 10Q in which grooves the pins carried by the links 28 and 28 areadapted to ride, the said pins being fixed to the threaders 18 and 18.By arranging the said pins to ride in the said cam-grooves the threadersare caused to partake ot' a rise-and-fall motion in their movement thatallows for the sewing-twine carried thereby being carried either aboveor below the eyes of the needles 1st and 14', as required in order tohave the needles catch the twine. On the drivers 26 and 2G are hooks 31and 3l', to which the rear ends of the springs 20 and 20' are secured,the forward ends of said springs being connected to hooks 32 and 32' onthe cam-groove containing standards 33 land 33'.

27 and 27' are tripping-blocks carried by the hand-levers 15 and 15,said blocks being arranged on the levers in such positions that when theforward ends of the levers are moved outwardly the blocks will becarried against the dogs 2l and 21 and coming in contact with said dogstrip them.

36 and 36' designate slotted arms projecting from the cam members 23 and23. The slots in these arms are adapted to receive pins 37 and 37 on thehand-levers 15 and 15', whereby the cam members may be swung on theirpivots in engagement with the drivers 26 and 26.

On the needles I have provided removable stop-plates 38 and 38', adaptedto limit the movement of the needles, the said plates being adapted'tostrike against the jaws 7 and 7 as the needles are carried inwardly.

In the operation of this machine it is required that the two sets ofneedles be alternately carried through the broom-straw and threaded anddrawn back, bringing the sewing-twine through the straw each time. It isfurther required that each stitch be of a determined length and that theneedles be fed through the entire thickness of the broom to receive thetwine. To arrive at the results above stated, I hold the broom-straw ina tixedy position between the jaws 7 and 7 and move the sewing devices.I take a bundle of straw and tie it looselyinto approximately the shapeof the broom to be made and clamp it firmly between the jaws by thetoggle 4 5. I then take a number ot' pieces of sewing-twinecorresponding to the number required to bind the broom, cut to therequired length, and passing each of them around the bundle of strawthrough the elongated slots in the jaws 7 and 7' secure one end of eachpiece of twine to a part of the straw, leaving a loose end of sufficientlength to be sewed throughout the entire width of the broom. The strawis at this time in condition for the sewing operation. In sewing I rstpass the needles 14 on the left-hand side ot' the machine through thebundle of straw by drawing the hand-lever 15 inwardly, so that the eyesof said nee; dles project beyond and through the straw. I then place theloose end ot' each piece of twine in the eyes of the needles 1t by handand push the said lever outwardly, carrying the needles, with the twinein the eyes thereof, through the straw to their first position. Whenthis has been done, the parts of the machine are in the position shownin Figs. 1 and 2, and the twine carried through the broom-straw has beendrawn, with the needles, into the slits in the rubber strips 19. Thehand-lever 15 is then drawn inwardly, and the needles 11i are carriedthrough the straw, when their eyes receive the sewing-twine by catchingthe said twine where it is upheld by the slitted strip 19 At this timethe threader 18 at the right-hand side of the machine is in rearposition. The hand -lever 15 is then moved outwardly, and the needles 14are drawn through the straw, carrying the twine therewith. Immediatelyupon the needles reaching the right-hand side of the broom the threader1S is released in the manner IOO IIO

herein described and at a time that will cause the said threader tostrike the needles. The consequent result is that the rubber strip 19 isforced onto the needles at the locations of the slits in said strips andthe needles enter said slits and carry the twine therewith. The movementof the needles being continued, they pass out of the strips; -but thetwine rc mains therein ready to be caught by the needles 14 as they aresubsequently brought through the broom in the sewing operation. lVhenthe lever 15 is moved inwardly, the pin 37, carried thereby, operates inthe slotted arm 36 and causes this arm and the cam member 23 to bemoved, so that the cam member is thrown rearwardly in Contact with therear end ot' the driver 26, carrying the driver rearwardly, and with itthe threader 18, against the action of the spring 20. The driver iscarried rearwardly until the stud 25 thereon engages the rear edges ofthe upright spring-post 24, where the driver is maintained for the timebeing. On the reverse movement of the handlever 15, which draws thetwine t-hrough the broom-straw, the pin 37 operates in the slot of thearm 36, causing the cam member 23 to be moved forwardly against thespring-post 24, throwing the post to one side and carrying the stud 25from the spring-post, so that the driver is released and may be drawnforward by the spring 2O and carry the threader 18 correspondingly, sothat the twine carried thereby in the slits of the strip 19 is againbrought to the position to be caught by the needles 14', when they arecarried through the straw in the same manner as that first described. Asthe needles let are carried through the straw the threader 18 is carriedbackward by reason of the driver 26/ being engaged by the cam member23', operated in like manner to that described in connection with thecorresponding parts at the opposite side of the machine. Theseoperations are carried on in the manner stated through the entire sewingof the broom, each set of needles being alternately carried inward andoutward to draw the sewing-twine backward and forward through the straw.threader 18 or 18 at either side of the machine is permitted to moveforward by the driver being disengaged from the spring-post 24 or2e' thedriver moves forwardly under the impelling power of the spring 20 untilit is caught by the dog 21 or 2l', and the parts are retained in thisposition until the handlever being moved is thrown outwardly to aposition where the tripper-block 27 or 27 is brought against the dog 21or 2l and releases said dog from engagement with the driver, permittingthe threader to be projected forwardly under the action of the spring 2Oor 20. As the threader moves forwardly the pin 28, connecting thethreader and the links 28 and 28, rides in the cam-grooves 29 and 29',carrying the twine under or over the needles, according to the side ofthe machine at the time being operated.

Each time the The two sides of the machine are identical except in thatthe cam-grooves 29 and 29 are reversed from each other, so that thethreader at the right-hand side of the machine may ride upwardly in itsforward movement, and the threader at the left-hand side may ridedownwardly in order to allow the needles on the right-hand side toreceive the twine in their eyes, which open downwardly, while theneedles at the opposite side of the machine have their eyes openupwardly.

Each time that the hand-levers 15 and 15 are moved outwardly to theirfullest extent the rear ends of the levers are brought against the innerparts of the braces 35 35,which serve as stops. The continued pressureagainst the hand-levers causes the slides 10 and 10 and the partscarried thereby to be moved rearwardly, the movement effected each timebeing the extent of one ofthe notches of the teeth 11 11', so that theneedle-carriers are moved rearwardly a corresponding distance to presentthe needles to the broom at the location of the next stitch to beproduced in the broom.
